ANDREW M. MORRISON, OF DUBUQUE, IOWA.

AUTOMATIC BARREL-FILLER.

T 0 all whom it may concern Be it known that I, ANDREW M. MORRISON, a citizen of the United States, and a resident of the city of Dubuque, in the county of Dubuque and State of Iowa, have invented certain new and useful Improvements in Automatic Barrel-Fillers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numbers of reference marked thereon, which form a part of this specification.

In the filling of bottles, barrels, and the like, it is desirable to measure the quantity of liquid to be delivered into barrels or bottles to insure filling the receptacle withcut overflowing the same, and spilling a portion of the liquid.

The object of this invention is to afford a construction by the use of which bottles, barrels, or other containers may be filled to the desired extent without danger of overflowing and with a certainty of the supply being shut off when the requisite amount of the liquid has been delivered into the container. It is also an object of the invention to afford a construction wherein a spring pressed supply valve is supported in open position during the filling operation and is automatically tripped to close immediately upon the liquid reaching a predetermined height in the container. It is an object of the invention to afford a construction whereby exceedingly sensitive tripping mechanism for the valve is afforded, adapted to be operated by the riseof the liquid in the container. It is a further object of the container to afford a construction of an exceedingly compact and durable character, adapted to act automatically to limit the height to which a liquid can be delivered therethrough into a container.

The invention (in a preferred form) is illustrated in the drawings, and hereinafter more fully described.

In the drawings: Figure 1 is a View in elevation of a device embodying my invention, and illustrating its use. Fig. 2 is an enlarged central vertical section of the same. Fig. 3 is a section on line 33 of Fig. 2. Fig. l is a fragmentary detail section thereof illustrating the tripping means. Fig. 5 .is a section on line 5-5 of Fig. 2.

charged into barrels, bottles or other contamers.

2, indicates a barrel shown as being filled with the liquid from the tank, and inserted' into the bung-hole of which is the discharge hole of a filler embodying my invention, and which is connected with the receptacle or tank 1, by means of a suitable hose 3, or other suitable connection. Said filler comprises a tube or pipe 4, of a size adapted for insertion into the bung-hole or other filling receptacle of the container to be filled, secured within which, and eccentricallythereof, is a float chamber 5, which extends from the lower end of the tube 4, upwardly to near the top thereof and is closed at its upper end. Said tube l, and the chamber 5, are slotted along their lines of contact from the lower end thereof to near the upper end of said chamber 5 and freely slidable in said chamber is a float 6, which is closed at its upper end and open at its lower end. Secured near the upper end of said tube or pipe 4, and extending radially therefrom, is a bracket- 7, and pivotally engaged at the outer end of the bracket is a tripper lever 8, the end of which extends through the slot in the filler tube 4, and chamber 5, and is connected by means of a link 9, with the top of the float 6.

Threaded or secured in any suitable manner on the upper end of the pipe is a valve casing 10, having a transverse, and, as shown, conical valve seat 11, therein, dividing the same substantially into two chambers, in the upper of which, and adapted to close on said valve seat, is .a valve 12, complemental with said seat, A stem 13, is secured on said valve, and extends upwardly into a suitable guide sleeve 14, therefor integral with the cap 15, which closes the upper end of the casing, and engaged on said sleeve and stem and between said cap and the clo sure, is a coiled pushing spring 16, which acts to force said closure down upon the seat.

The lower end of said stem extends through a suitable guideway 17, at the center of the seat and is provided with a tapered recess therein to receive a pin 18, which is pivotally engaged on the inner end of an arm 19,

which is rigidly secured on a shaft 20, the two constituting a crank lever, said shaft 20 extending into said casing eccentrically therewith at a point above the bracket 7. Said shaft extends through a sleeve 21, in-

tegral with the casing, and is provided with a gland. 22, at its outer end to prevent leakage therefrom.

Rig-idly secured on the outer end of the shaft 20, is an arm 23, the free end of which extends to the pivoted end of the tripping lever 8, and is suitably shaped to engage an inclined shoulder 24, thereon. whereby the weight of the tripping lever S, and the float hell 6, suspended thereon, is sufficient to hold the arm 23, in engagement therewith with the valve 12, elevated.

Communicating in the upper chamber of the casing, is a branch. pipe 25, which is threaded or otherwise form-ed to permit eng1 gement with the hose pipe 3, or other suitable connection with the storage tank from which the liquid is to be drawn.

The operation is as follows: Having connected the inlet 25, with the pipe 3, the arm 23, is pressed down *ardly to unseat the valve 12, as shown in Fig. 2, and the free end thereof is engaged in the inclined shoulder El in the tripping lever 8, the weight of the float bell and the tripping lever 8, being sufficient to hold said arm 23, in engagement in said shoulder. The valve now being open, the liquid flows from the tank or receptacle 1, through the pipe 3, and the filling pipe 4, into the barrel or other receptacle or container, and rising therein, at last reaches the lower end of the float G, contining the air therein, and as the liquid rises in the receptacle or container, raises the float. The slotted walls of the filler tube 4t and float chamber 5 permit the liquid to freely enter the chamber 5 to carry the bell or float up ardly therewith. The link 9, communicates the upward movement of the bell to the tripper lever 8, throwing the inner end of said lever upwardly and thereby causing the shoulder 24, to recede from the end of the arm 23, releasing said arm and permitting the valve to close under the impulse of its spring. Inasmuch as the shoulder 24:, re cedes from the end of the arm 23, it is evident that the mechanism will act accurately even though used with liquids of a thick or gummy nature which might possibly otherwise at times interfere with the operation of such a device. The release of said arm 23, of course, permits the valve to immediately close under the pressure of its spring, thus shuttingoff the flow. The filler may now be safely removed from the barrel or container and applied in the filling aperture of another container, and the operation repeated. The tripper lever 8, being exposed for manipulation, can readily be manipulated after the insertion of the end of the filler into the barrel, and having been raised to the proper position, the arm 23, is forced downwardly into engagement with the shoulder 24, and the operation is repeated.

An exceedingly sensitive release is afforded by the construction described, and it is obvious that the height to which the liquid can rise in the container is in all in stances positively and automatically limited. Of course, details of the construction may be varied, and I therefore do not purpose limiting the claim of this application otherwise than necessitated by the prior art.

I claim as my invention:

A filler for liquid containers, ei'nbracing 2r filling pipe, an inlet pipe opening thereinto, a spring pressed valve in said filling pipe closing below said inlet pipe, a float in said filling pipe, a pivoted tripper lever connected therewith and having an obliquely directed shoulder above its pivot, a. crank lever fulcrumed in said filling pipe to one side of the line of movement of said valve and adapted to support said valve in open position against its spring, and an arm fixed to said crank lever and shaped at its free end to engage the obliquely directed shoulder on the tripper lever to hold the valve in open position, said shoulder receding from and releasing said arm as its lever is turned by the upward movement of the float.

In testimony whereof I have hereunto subscribed my name in the presence of two subscribing witnesses.
